FIELD: light-sensitive materials. SUBSTANCE: composition contains, wt. -%: vinylidene chloride/acrylonitrile/methyl methacrylate copolymer or mixture of vinylidene chloride/acrylonitrile copolymer with poly(methyl methacrylate) (weight ratio 4:1), 15.94-16.55; 4- diazo-N,N-diethylaniline borofluoride or 4-diazo-2,5- diethoxyphenylmorpholine borofluoride, 1.53-1.67; acetone, 66.7-73.2; and ethyl Cellosolve or methyl Cellosolve, the balance. Composition allows its preparation time to be reduced by 168 h and toxic solvent to be avoided. Composition can be used to prepare vesicular materials applicable for copying microfilms. EFFECT: speeded up preparation and improved environmental condition. 1 tbl |
